Abstract This data set contains count rates (1/s) as measured by the Standard Radiation Environment Monitor (SREM) instrument on the Rosetta spacecraft, along with their standard deviations. The primary target is comet 67P/Churyumov-Gerasimenko. These are CODMAC Level 2 Experiment Data Record data, and provide a measure of the radiation in the spacecraft environment during the Medium Term Plan 4 period of the PRELANDING mission phase.
Description Data Set Overview = This data set contains 'raw' SREM count rate data (1/s), converted from the equivalent SREM Level 0 CDF products, which are provided in the EXTRAS directory. Note that the CDF processing levels differ from the CODMAC definition used within these PDS data sets. The SREM CDF Level 0 data are equivalent to the PDS CODMAC Level 2 data while the SREM CDF Level 2 data are equivalent to the PDS CODMAC Level 5 data. Associated standard deviations are also provided within each data product, calculated as the square root of the count rate values. These data are useful for determining the energetic particle environment experienced by the Standard Radiation Environment Monitor onboard the Rosetta Orbiter. Processing These are 'raw' count rate data converted directly from the equivalent SREM Level 0 CDF data. No additional processing has been completed. Standard deviations are provided within each data product, along side the data, and are calculated as the square root of the count rate values. Data One data product is provided per day of measurement. Data products are named according to the following convention: SREM_L_YYYYMMDD.EXT Where: is the CODMAC processing level (2 for the count rate data and 5 for the derived proton and electron flux data). YYYMMDD is the date of the observation. EXT is the file extension (TAB for the ASCII data table and LBL for the detached PDS label file). All data products are formatted as plain ASCII tables and have an associated detached PDS label. The CODMAC Level 2 data are given as count rates (1/s) for each of the 15 SREM energy bins, and their associated standard deviations (calculated as square root of the count rate). Measurements are time tagged at the middle of the time interval (centered). The following table provides a list of the 15 SREM channels and the corresponding energy ranges of detected protons and electrons. ||...

The spacecraft carries a Rosetta Lander, named Philae, to the nucleus and deploys it onto its surface. A brief description of the mission and its objectives can be found in [GLASSMEIERETAL2007A]. A detailed description of the mission analysis can be found in the ROSETTA User Manual [RO-DSS-MA-1001], and the flight Operations Plan [RO-ESC-PL-5000]. On its long way to the comet nucleus after a Launch by Ariane 5 P1+ in March 2004, the ROSETTA spacecraft orbited the Sun ...
